Description

In moving to 0.16, which will support permissions, a mode of no-permission checking has been proposed to allow smooth transition to using the new permissions feature.
The idea is that at first 0.16 will be used for a period of time with permission checking off.
Later after the admin has changed ownership and permissions of various files, the permission checking can be turned off.

This Jira defines what the semantics are of the no-permission-checking mode.
